Question

The dimensions of a cuboid is equal to double the dimensions of another cuboid. Find the ratio of their volumes.

Answer 1

Let the dimensions of second cuboid be x,y,z .

Now ,The dimensions of first cuboid is 2x,2y,2z

Volume of first cuboid = 2x*2y*2z=8xyz .
Volume of second cuboid =x*y*z .

Therefore ,Ratio of the volumes =8xyz:xyz = 8:1 .
